Application March 24, 1933, Serial No, (562 624 2 Claims,

This hivention relates to a control device for oil and and tor pipe lines, the general ohlect of invention being to provide means for extinguishing fires in oil and gas wells, for capping such wells and gas or water lines and for stopping leaks in pipe lines without cutting on water, gas or oil.

This invention also consists in certain other features of construction and in the combination and a ran enient oi the several parts, to be hereinaiter fully described, illustrated in the accon'e= panying drawnigs and specifically pointed out in the appended claims. I

in describing the invention in detail, refer= ence will he had to the accompanying drawings wh rein like characters denote like or correspond= parts throughout the several views, and in whichz- Figure l is an elevation of the device.

igure 2 is a similar view hut talren at rig t *s to Figure l.

igure 3 is a longitudinal sectional through the device.

Figure l is a section on line or" Figure l. Figure is a section on line 5-5 of Figure 1. Figure 6 is a detail sectional view showing how a pipe is closed by a part of the device.

Figure 7 is a fragmentary view looking into section of the casing and showing one or the pressing members.

Figure 3 is a sectional detail view through one of such members.

hi these drawings, the letter A indicates a casing formed of a cylindrical part with conical ends, the casing being formed of two sections 1 and 2 provided withflanges 3 which are bolted together, as shown at i, with a gasket 5 between the flanges. Each end of the casing is formed with a reduced cylindrical part 6 through which 48 the pipe or well casing 7 passes.

in the cylindrical part of the casing, at diametrically opposite points, internally threaded bushings 8 pass through holes in the casing and these bushings are held in position by the loclr 5 nuts 9 and the packing caps to which are located enteriorly of the casing. it screw shaft ll passes through each bushing and has a hand wheel 12 at its outer end. The inner end oi each shalt is formed with a spherical part 13 which fits in a so socket in a member it which carries a plate-like part 15. Thus the members it and 15 are rotat= aloly arranged on the inner end of the shaft ll. and are held against rotary movement by the guide bars 16 arranged in the casing, so that these members is and 15 can be moved toward positelv arranged holes in the cylindrical part oi the casing, as shown in Figure 3, and are held in place hy the loclr. nuts l8 and the caps 19. A screw shaftzll passes through each of the bushings it and is provided with a hand wheel ill at its outer end and its inner end is formed with a bit 22 so that Toy turning these shafts 2o inwardly, they will here a pair of oppositely arranged holes in the pipe 7, as shown in Figure 5, Then by hacking the shaft, water or other fluid will pass from the pipe into the casing and fluid in the casing will pass into the pipe through these holes. A nipple 2311s screwed into the top part of the casing and a checlr valve 24: is lastened to the nipple and a hose 25 is connected to the valve so that rluid can he introduced into the casing. A. drain pipe as is connected with the bottom part of the casing and contains valve 2? so that the owing can he drained whenever necessary. a gauge 28 is fastened to the top of the casing and a plurality of pipes 29 is connected with the cylindrical part of the casing and each contains a valve to. A valve 3i is also con= nected to the lower part of the cylindrical por== tion of the casing by a pipe 32. These valves, when opened, will permit pressure to escape from the casing alter the holes are bored in the pipe "i and by opening one valve at a time, one can ascertain just how much pressure there is in each valve line in? watching the pressure gauge at and "or; closing all of the valves, the pressure gauge a; show how much pressure there is in the well or pipe line. By opening the valve 2?, any sediment or the hire in the casing will he drained therefrom.

In using the device to extinguish a hing well, a tunnel would be dug to reach a part of the well casing a sumcient distance below the ground to avoid heat from the lire. The casing is then attached to the exposed part of the well casing and the same filled with water or chemicals through the hose 25. This water or chemicals will prevent any sparks occurring while the ls are being used to bore holes in the pipe or casing 7. In some cases, the water or checals introduced into the casing by the hose 25, entering the holes in the pipe 7, will extinguish theme, but if the pressure from the introduction of the fluid into the casing through the hose 25 is not great llll enough to extinguish the fire, then the pressers are used to press the pipe, as shown in Figure 6, to close the same so that the oil or gases are shut off at the top of the well and thus the fire is ex- 5 tinguished. Then by attaching a pipe or hose to the valve 31 or one of the other pipes 29, the fluid entering the casing from the pipe 7 through the holes bored therein can be conveyed to any desired point. In case the well should catch fire a second time, all that is necessary is to close the globe valve to which the conveying pipe is conneeted.

This device can also be used to cap an oil or gas well as soon as the well is brought in by attaching the machine to the well casing before the well is brought in. When the well is brought in, the pressers are first used and when the flow is cut off, the drills are used so that the oil or gas will flow into the casing. Then the valve attached to the flow line can be opened so that the flow will pass to the desired point.

This invention will cap any oil, gas or water line without cutting off the water, gas or oil pressure. By clamping the device on the pipe and by using only one drill and the globe valve, the flow can be conveyed to the desired point.

The device can be also used to stop leaks in any water, oil or gas line by clamping the device over the leak so that the leakage will be caught by the device.

The valve 31 may have a pipe 31' attached thereto and a cap 33 may be placed on the upper end of the pipe '7 after the well has been cut oil by the pressers if there is any leakage past the pressers.

It is thought from the foregoing description that the advantages and novel features of the invention will be readily apparent.

It is to be understood that changes may be made in the construction and in the combination and arrangement of the several parts, provided that such changes fall within the scope of the appended claims.

What I claim is:-

1. A device of the class described comprising a casing, a pair of oppositely arranged threaded shafts carried thereby, presser members at the inner ends of the shafts and rotatably supported thereby for pressing and closing a portion of a pipe passing through the casing, a shaft passing through the casing and having a bit at the inner end for boring a hole in the pipe, means for rotating the shafts, means for introducing fluid into the casing and valve carrying pipes connected to the casing.

2. A deviceof the class described comprising a casing, a pair of oppositely arranged threaded shafts carried thereby, presser members at the inner ends of the shafts and rotatably supported thereby for pressing and closing a portion of a pipe passing through the casing, a second pair of oppositely arranged threaded shafts passing through the casing and having bits at the inner ends for boring holes in the pipe, means for notating the shafts, means for introducing fluid into the casing, valve carrying pipes connected to the casing, a pressure gauge attached to the casing and a drain valve connected to the bottom part thereof.
